Laser gas analyzers play an important role in managing security, safety and operational performance, including applications in the chemical and metal industries, in waste facilities and power plants as well as in glass and PVC production, and many more. They rely on non-contact, optical measurement methods to detect for temperature variations, high dust levels, or corrosive gases in process conditions. Generally these devices are described as sensors.

One product is the Lasergas II, produced by NEO Monitors which feature two versions of the Imsys SNAP controller module with IM3000 MCU. Lasergas II is an analyzer designed for monitoring flow and condition of gases. The product offers low total cost of ownership suitable for a wide range of demanding process conditions. It offers one-second response time with very low detection limits and comes with Ethernet connectivity.
